Right-wing conspiracy theorist Alex Jones and Nation of Islam leader Louis Farrakhan are running out of places to espouse their views online.

Facebook banned these high-profile personalities and several others from its social media platforms Thursday, becoming the latest tech company to officially declare them persona non grata. Many of them have already been banned from Twitter, YouTube and Apple's Podcasts app.

In addition to Jones and Farrakhan, Facebook also kicked out right-wing extremists Milo Yiannopoulos, Laura Loomer and Joseph Watson, who works for InfoWars; white supremacist Paul Nehlen, who unsuccessfully ran for Congress in 2016 and 2018; and Jones's company, Infowars. The groups will also lose their accounts on Instagram, which is owned by Facebook.

"We've always banned individuals or organizations that promote or engage in violence and hate, regardless of ideology," Facebook said in a statement, according to The Verge. "The process for evaluating potential violators is extensive and it is what led us to our decision to remove these accounts today."

Facebook bans "dangerous individuals and organizations" that engage in violence or have an ideology that attacks individuals based on race, religion, ethnicity, or sexual orientation. A Facebook spokesperson told CNN that the company undergoes a lengthy review process before a ban, looking at factors such as whether someone has called for violence, and whether they use hateful slurs to describe themselves in their "About" section.

Jones told The Washington Post that Facebook's actions were "authoritarian," saying that they never gave him any direct notice that they found his posts "dangerous."
